- * Name: net_initialize
- *
- * Description:
- * This is called from the OS initialization logic at power-up reset in
- * order to configure networking data structures. This is called prior
- * to platform-specific driver initialization so that the networking
- * subsystem is prepared to deal with network driver initialization
- * actions.
- *
- * Actions performed in this initialization phase assume that base OS
- * facilities such as semaphores are available but this logic cannot
- * depend upon OS resources such as interrupts or timers which are not
- * yet available.
- *
- * Input Parameters:
- * None
- *
- * Returned Value:
- * None
- *
